T o all ahom it may concern.:

Be 1t known thatl I. Louis ERBE, a citizen of the Umted States, residing at Blame, 1n

the county of 'hatcom and State of 'ashington, have invented a new and useful Bilge-ll'ater Ejector, of which the following is a specification..

This. invention relates to means for eject: ingbilge .water from boats while they are in motion, said. means dispensing with the use of pumpsl or other means such as usually em ployed for removing the water from the hull of a boat.. A

The object of the invention' is to providean ejector of this' character which can be readily attached to the hull of a boat. and, when in position, will not detract from the appearance of the boat' or retard its movements. l

A further object is to provide means of this characterwhich will automatically operate during the movement of the boatto withdraw bilge water therefrom, the ejector be ing designed to close automatically when the `boat is not. in motion so as 'to prevent water from entering the boat through the ejector.

'ith these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will4 be hereinafter more fully described and pointed out in the claims.

In the. accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a side elevation of -a portion of a boatand showing the present improvements ap lied thereto. Fig. '.2 is an enlarged section t irough a portion of the boat-and through the attachment. Fig. 3 is a transverse section through the rear portion ofthe attachment and the adjoining ortions of the boat. Fig. 4 is a plan view o the Referring to the figures by characters of reference, 1 designates the hull 0f a boat which-may be of any sultable size and pro- Aportions and secured tothe rear portion of thevbilge is the attachment embodying the lpresent improvements. This attachment consistsof a tubular body 2 fastened preferably to the rear portion o f theY keelythere being and the ends of the dy are open. rojecting into the forward end .of thevbody and -formed integral therewithis an' outlet tube surface of the bilge.

' 4 eccentrically located in relation to the body Y so as to form a crescent-like inlet 5 therebelow and opening into the body 2. VIf desired, suitable brackets 6 may extend from the tube 4, these brackets being fastened' to the keel, The forward end of tube 4 is ex- 60 tended upwardly in the formof an ell as indicated at 7 and has an annular collar 8 designed to bear against the outersurface ofthe biigewhile'the terminal portion of the tube is screw threaded as indicated aty 9 and de- 65 signed to project into an opening l() formed within the bilge. This threaded end may be fastened in place in any preferred manner as by utilizing a threaded sleeve 11 which is insertiblc into the opening and has a collar 12 designed to bear upon the inneror upper The two collars 8 and 12 may b'e iirmly clamped upon the bilge by means' of bolts 13. Itis of cours'eto be undelstood that if desired other means for fastoning the ell 7 to the boatmay be utilized. That portion 7 of the tube 4 which extends. upwardly to the bilge is slight-ly reduced in size so as to form a seat 14 for a valve 15 located at one end of a lever- 16. This lever extends throughout the length of the tube 4- and is pivoted adjacent. the rear end of the tube between ears 17. That portion of the lever projecting into the body 2 is broadened to form a blade 1S and this blade is designed; 85 when the valve 15 is upon its seat., to extend downward diagonally across the body 2 and in rear o f the crescent-shaped inlet 5. s

The normal positions of the valve 15, lever 16, and blade 1S has been indicated by dotted 90 lines in Fig. 2. The valve is held normally seated in this manner by reason of the fact thatl the blade 18 acts as a weight to hold the valve raised. These positions of the arts are assumed when the boatl is atI 'a stan still. 95

AWhen the boat is propelled forward by an suitable means the water will' pass throng the inlet 5 as indicated b v arrows in Fig. 2 and will strike against the blade 1S, thus elevating itand causing the valve 15 to swing 100 downward. The water will pass entirely through the body 2 and will create a partial ,j n

' vacuum'within saidbody and the tube 4 and j y cause any bilge water to flow downward into i the tube 4 and outward with the current. 105 'suitable brackets )rovlded forthis purpose `moved and .the valve willthusbe 'meto v swingV into closed position.

It will be understood that thev movement of the valve will lbe in proportion to the speed of the boat and consequently the extent of the vacuum produced so that there is absolutely no danger of th'e'val've being opened to such an extent as to allow water to enter the boa-t through-theopening 10:'

It will be seen that the device is very simple, durable, and eii'cient and can be a plied to the hull of a boat with little troub e.

Although only one of l.these attachments has been' illustrated in connection 'with a. boat it is to. be understood that tvro vor' more mayv be empltivedjf desired, according to the.

size of-the hull 'and to the tasteof the user, The parts ,2 and 4 can be of any desired Vcross sectional contour so as vto fit snugly mainst the boat.

Tlie'attachment is designed to be used 4in connection with various forms of boats such as scows, or large shipsjas fell as small rowboats and the like.

hat is claimed is: A l

1. An attachment of the character described comprising an outlet tube, a tubular I body extending beyond one en d of said tube and having an outlet at one end and a re duced inlet opening at its otherend and belowv the tube, said tube being disposed to be connected to the bilge of a boat-, a valve, and a gravity operated member for holding the valve normally upon its seat to close the inlet of the tube, said gravity operated member being disposed within the body and between the red1 tcedinlet and thefoutlet thereof.

:2. An attaclnnent of the character. described comprising an out-let tube, ,a tubular ,body extending beyond one end of said tube and having an outlet at one end and a reduced mlet opening at its' other end and below the tube, Ysaid tube being disposed to be` connected to and to communicate with the interior ofv the hull of av boat, a valve for closing the inlets of said tube, a lever extending therefrom and fulcrumed within the tube,

and a combined blade and Weight at one end of the lever and extending into the body and betiveen the reduced inlet and the outlet thereof.

3. An attachment of the character described lcomprising; anoutlet tube, a tubular body at. the discharge end of said tube, said body having a reduced inlet adjacent the discharge end of the tubev and an outlet, a valve, and means operated bythe passage of water through the body. for opening the valve.

4. An attaclunent of the character described comprisingan outlet tube, a body extending therebeyond and having an. outlet at i oneend and a reduced inlet at the other end and adjacent the discharge end of the tube, a-

valve normally closing the inlet end of the tube, and means operated' by the ressu're of Water assing'through the body or opening the va ve. i A

5.' The combination with the hull of a Y boat; of an outlet tube extending rearwardly therefrom, a tubular body partly surrounding the discharge end of said tube 'and having anoutlet at its rear end' and a reduced inlet va ve normally seated inthe'inle't'poition of the tube, and a combined Weight-and' blade movable with the valve and dis osed Within the body,said blade being normal vinter osed between'the inlet and outlet of the bot y.

l6. An attachment of the character described comprising an outlet tube, a valve within the tube and normally closed by gravity, and means connected to the valve and mounted toV move within the tube for o ening the valve durinfr the movement of t e attachment in one direction through a body of water.
